SER Serina Therapeutics Inc

Serina Therapeutics, Inc. (“Serina”) (NYSE American: SER), a clinical-stage biotechnology company advancing its lead IND candidate SER-252 for advanced Parkinson's disease, enabled by its proprietary POZ Platform™ drug optimization technology, today announced its financial results for the third quarter ended September 30, 2024, along with key recent updates.

Recent Highlights

• Partnership and Presentations with Enable Injections: Building on its collaboration with Enable Injections, Serina presented a case study at the 14th Annual Injectables Summit in Boston, MA, detailing the combination of Serina’s lead candidate, SER-252 (POZ-apomorphine), with Enable’s enFuse™ wearable drug delivery platform. This innovative partnership aims to enhance patient comfort and convenience, providing continuous dopaminergic stimulation (CDS) for Advanced Parkinson's Disease patients through easy-to-administer subcutaneous injections.

Third Quarter Operating Results

Revenues: Revenues comprised entirely of grant revenues from the National Institutes of Health in the amount of $14 thousand and $29 thousand for three months ended September 30, 2024 and 2023, respectively.

Operating expenses: Operating expenses for the three months ended September 30, 2024 and 2023 were $5.3 million and $1.5 million, respectively.

Research and development expenses for the three months ended September 30, 2024, increased by $1.8 million to $2.4 million as compared to $0.6 million for the same period in 2023. The net increase was primarily due to $0.8 million in salaries and payroll related expenses due to increase in headcount, $0.5 million in professional fees for the maintenance of certain patent and other intellectual property and biological material assets included in Legacy Assets, and $0.5 million in outside research services and consultants for research programs.

General and administrative expenses for the three months ended September 30, 2024, increased $2.0 million to $2.9 million as compared to $0.9 million for the same period in 2023. The increase is attributable to increases of (1) $0.9 million of stock based compensation expenses as a result of new directors and new hire option grants, (2) $0.5 million of consulting expenses to assist with the implementation of new platforms and software, (3) a non-recurring $0.3 million severance expenses (4) $0.2 million in compensation and related expenses as a result of increased headcount (5) $0.2 million in directors and officers insurance, and (6) $0.2 million in miscellaneous expenses that were individually insignificant. These expenses were offset by a decrease of $0.3 million in professional legal and accounting services incurred largely in connection with the Merger which consummated on March 26, 2024.

Other income, net for the three months ended September 30, 2024 increased $3.5 million to $6.7 million as compared to $3.2 million for the same period in 2023. The increase was primarily attributable to an increase of $6.1 million in the gain from the change in fair value of liability classified Merger Warrants offset by the loss in the fair value of the Legacy Serina Convertible Notes and the AgeX-Serina Note of $2.6 million.

Net income: The net income attributable to Serina for the three months ended September 30, 2024 was $1.4 million, or $0.16 per share (basic) and $0.13 per share (diluted) compared to net income of $1.8 million, or $0.80 per share (basic) and $0.23 per share (diluted), for 2023.

Liquidity Information

Cash, cash equivalents, and restricted cash totaled $3.2 million as of September 30, 2024.

Going Concern Considerations

As required under Accounting Standards Update 2014-15, Presentation of Financial Statements-Going Concern (ASC 205-40), the Company evaluates whether conditions and/or events raise substantial doubt about its ability to meet its future financial obligations as they become due within one year after the date its financial statements are issued. Based on the Company’s most recent projected cash flows, the Company believes that its cash and cash equivalents of $3.2 million as of September 30, 2024 with the approximately $10 million of cash proceeds expected to be received from Juvenescence through the exercise of Juvenescence’s remaining Post-Merger Warrants as provided in a “Side Letter” would not be sufficient to satisfy the Company’s anticipated operating and other funding requirements for the twelve months following the filing of the Company’s Quarterly Report on Form 10-Q for the three and nine months ended September 30, 2024. These factors raise substantial doubt regarding the ability of the Company to continue as a going concern.

About SER-252 (POZ-apomorphine)

SER 252 is an investigational apomorphine therapy developed with Serina’s POZ platform and designed to provide continuous dopaminergic stimulation (CDS). CDS has been shown to reduce the severity of levodopa-related motor complications (dyskinesia) in Parkinson’s disease. Preclinical studies support the potential of SER 252 to provide CDS without skin reactions. Serina plans to advance SER 252 to clinical testing in 2025.

About the POZ Platform™

Serina’s proprietary POZ technology is based on a synthetic, water soluble, low viscosity polymer called poly(2-oxazoline). Serina’s POZ technology is engineered to provide greater control in drug loading and more precision in the rate of release of attached drugs delivered via subcutaneous injection. The therapeutic agents in Serina’s product candidates are typically well-understood and marketed drugs that are effective but are limited by pharmacokinetic profiles that can include toxicity, side effects and short half-life. Serina believes that by using POZ technology, drugs with narrow therapeutic windows can be designed to maintain more desirable and stable levels in the blood.

Serina’s POZ platform delivery technology has potential for use across a broad range of payloads and indications. Serina intends to advance additional applications of the POZ platform via out-licensing, co-development, or other partnership arrangements, including the non-exclusive license agreement with Pfizer, Inc. to use Serina’s POZ polymer technology for use in lipid nanoparticle drug (LNP) delivery formulations.

About Serina Therapeutics

Serina is a clinical-stage biotechnology company developing a pipeline of wholly owned drug product candidates to treat neurological diseases and other indications. Serina’s POZ Platform™ provides the potential to improve the integrated efficacy and safety profile of multiple modalities including small molecules, RNA-based therapeutics and antibody-based drug conjugates (ADCs). Serina is headquartered in Huntsville, Alabama on the campus of the HudsonAlpha Institute of Biotechnology.
